ObjectiveTo observe the clinical efficacy and safety of Yishen Jiangtang decoction combined with conventional Western medicine treatment in managing stage G3A3 diabetic kidney disease （DKD） in the patients with the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis， and to explore its mechanism of inhibiting the endoplasmic reticulum stress （ERS）-apoptosis axis and delaying renal fibrosis （RF）. MethodsA single-center， randomized， parallel-controlled clinical trial was conducted. A total of 78 patients diagnosed with stage G3A3 DKD and traditional Chinese medicine （TCM） pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis and treated in the Department of Nephrology and the Department of Endocrinology of the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from March 2025 to February 2026 were enrolled. They were randomly assigned at a 1∶1 ratio into a control group （conventional Western medicine treatment） and an experimental group （Yishen Jiangtang decoction combined with conventional Western medicine treatment）， with 39 patients in each group. The treatment lasted for 12 weeks. Basic demographic data and medical history were collected before and after treatment. The two groups before and after treatment were compared in terms of the following parameters： Blood urea nitrogen （BUN）， serum creatinine （SCr）， estimated glomerular filtration rate （eGFR）， urinary albumin-to-creatinine ratio （UACR）， fasting blood glucose （FBG）， triglycerides （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C）. Enzyme-linked immunosorbent assay （ELISA） kits were used to measure serum glucose-regulated protein 78 （GRP78）， serum cysteinyl aspartate-specific protease-3 （Caspase-3）， and serum and urinary transforming growth factor-β₁ （TGF-β₁） levels before and after treatment. TCM symptom scores， TCM syndrome efficacy， and overall clinical efficacy were evaluated before and after treatment. Spearman correlation analysis was performed to explore the correlations of serum levels of GRP78 and Caspase-3， as well as serum and urinary levels of TGF-β1， with renal function， proteinuria， and glucose and lipid metabolism indicators in patients with DKD. In addition， safety indicators were also monitored. ResultsA total of 75 patients completed the study （38 in the control group and 37 in the experimental group）. ① Baseline data： The two groups were comparable in terms of sex and age， with no statistically significant difference. ② Efficacy outcomes： Compared with baseline levels， both groups showed reductions in BUN， SCr， UACR， FBG， TG， TC， LDL-C， and TCM symptom scores （P<0.01） and increases in eGFR level （P<0.01）. Moreover， the experimental group outperformed the control group in altering the indicators above （P<0.05）. Regarding TCM syndrome efficacy， the total response rate in the experimental group was 83.78%， which was higher than that （57.89%） in the control group （P<0.05）. Regarding overall clinical efficacy， the total response rate in the experimental group was 78.38%， which was higher than that （50.00%） in the control group （P<0.05）. ③ Mechanism outcomes： Compared with baseline levels， both groups showed declined serum levels of GRP78， Caspase-3， and TGF-β₁ and urinary level of TGF-β₁ after treatment （P<0.01）. Moreover， the experimental group showed greater declines than the control group （P<0.05）. The serum levels of GRP78， Caspase-3，and TGF-β₁ and the urinary level of TGF-β₁ in DKD patients showed positive correlations with BUN， SCr， UACR， and FBG and negative correlations with eGFR （P<0.05）. ④ Safety outcomes： Neither group showed drug-related adverse reactions， and laboratory safety parameters remained within normal ranges. ConclusionYishen Jiangtang decoction combined with conventional Western medicine treatment may safely and effectively alleviate clinical symptoms， correct glucose and lipid metabolism disorders， and protect the renal function in patients with stage G3A3 DKD and the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis. The mechanism may be associated with inhibition of the ERS-apoptosis axis and delay of the RF process.

Objective: To study the current situation of sleep quality of senior high school students and analyze the influencing factors, so as to provide a reference for targeted sleep quality improvement of high school students. Methods: A total of 4 793 senior high school students of different grades were recruited from four different regions (Shanghai, Qinghai, Macao, Henan) in 2020. The information of demographic, sleep status, mental factors, living habits and other information were collected by questionnaire. Descriptive statistics and Logistic regression were used to analyze sleep quality and its influencing factors of the senior high school students. Results: About 24.2% of senior high school students reported sleep problems and 71.4% slept less than 7 hours at night. Interpersonal sensitivity, depression, anxiety symptoms, learning, family and interpersonal stress had significant effects on sleep problems in senior high school students( χ 2=1 147.98, 1 228.35, 1 032.54, 371.05, 497.61, 475.39, P <0.01). Drinking coffee and tea, drinking alcohol, smoking (including secondhand smoke), long term use of electronic products, late sleep, bedtime diet, poor sleep environment, parents with sleep problems were the risk factors for sleep disorders of senior high school students, regular exercise was the protective factors for sleep disorders of senior high school students, the influence was significant ( χ 2=160.28, 127.73 , 108.02, 113.27, 470.91, 340.95, 72.02, 155.53, 116.30, 76.96, 28.75, 12.89, P <0.05). Conclusion The sleep quality of senior high school students needs to be improved. Schools and parents should pay attention to the mental health and living habits of senior high school students to help them improve their sleep quality and grow up smoothly.

Protein self-assemblies at the micro- and nano-scale are of great interest because of their morphological diversity and good biocompatibility. High-throughput screening of protein self-assembly at different scales and morphologies using protein crystallization screening conditions is an emerging method. When using this method to screen protein self-assembly conditions, some apparently transparent droplets are often observed, in which it is not clear whether self-assembly occurs. We explored the interaction between β-lactoglobulin and the protein crystallization kit Index™ C10 and observed the presence of micro- and nano-scale protein self-assemblies in the transparent droplets. The diverse morphology of the micro- and nano-scale self-assemblies in the transparent droplets formed by mixing different initial concentrations of β-lactoglobulin and Index™ C10 was further investigated by scanning electron microscope. Self-assembly process of fluorescence-labelled β-lactoglobulin was monitored continuously by laser confocal microscope, allowing real-time observation of the liquid-liquid phase separation phenomenon and the morphology of the final self-assemblies. The internal structure of the self-assemblies was gradually ordered over time by in-situ X-ray diffraction. This indicates that the self-assembly phenomenon within transparent droplets, observed in protein self-assembly condition screening experiments, is worthy of further in-depth exploration.

Objective: To compare the mutation status of epidermal growth factor receptor (EGFR) between different lesions and clini-cal characteristics of synchronous multiple ground-glass nodules (SMGGNs). Methods: A retrospective analysis was conducted using clinical data from 35 patients with SMGGNs who were admitted to and received surgery at The Fourth Hospital of Hebei Medical Uni-versity Hospital from January 2017 to December 2018. Next generation sequencing (NGS) was performed for all surgical specimens to detect the mutation status of exons 18, 19, 20, and 21 of the EGFR gene to analyze the relationship between the EGFR mutation sta-tus of the lesions and patient gender, age, lesion location, imaging manifestation of nodules, and adenocarcinoma pathological type . Results: The EGFR mutation rate was 65.7% (23/35 patients). Non-smoking patients and females had higher EGFR mutation rates (P=0.015, P<0.001). The EGFR mutation rate of invasive adenocarcinoma nodules was higher than those of atypical adenomatous hyper-plasia, adenocarcinoma in situ, and minimally invasive adenocarcinoma ( P<0.001). Exon 19 deletion and L858R mutation were the most common mutations of the EGFR gene. There was no significant difference between the pathological subtypes of adenocarcino-ma and the EGFR mutant subtype (P=0.707). Among the 27 patients with multiple nodules with detectable EGFR mutations, the EGFR mutation rate was 85.2% (23/27 patients). Conclusions: The EGFR gene mutation status is different in patients with multiple pulmo-nary ground-glass nodules, suggesting that the occurrence and development of each nodule are independent events. EGFR gene muta-tion is closely related to the development of ground-glass nodules, especially in the invasion of tumors.

Objective To discuss the influence of psychological education on the resourcefulness of perioperative breast cancer patients. Methods Two hundred breast cancer patients from a first-class hospital in Fujian province were randomly assigned to the control group, in which routine care was done, and an intervention group, in which psychological education curriculum was employed at three stages on the basis of routine care. The resourcefulness scale was used in both two groups before and after the intervention to evaluate the score of individual and social resourcefulness and the total score of resourcefulness in these two groups. Results As to the control group, the score on individual resourcefulness and the total score on resourcefulness before and after the intervention had no significant differences (P>0.05), but the difference in the social resourcefulness scores before and after the intervention was statistically significant (P<0.05). The differences in the scores on the individual resourcefulness, social resourcefulness and the total score on resourcefulness in the intervention group before and after the intervention were all statistically different (P<0.001). What′s more, the scores of individual resourcefulness, social resourcefulness and the total score of resourcefulness between these two groups after the intervention were statistically different (P<0.001) as well. The scores of the intervention group were significantly higher than those of the control one. Conclusion The psychological education can significantly improve the resourcefulness level of perioperative breast cancer patients, which can help individuals to manage stress effectively.

Objective To explore the effects of diversified continuing nursing on recovery of patients with breast cancer after modified radical mastectomy. Methods A total of 90 patients with breast cancer after modified radical mastectomy were divided into observation group ( 45 cases ) and control group ( 45 cases ) according to random number table method. Patients in two groups received health guidance before leaving hospital, while those in observation group also received continuing nursing after leaving hospital. One month after leaving hospital, recovery of flaps and function of affected upper limb were evaluated. Results The flaps recovery of patients in observation group were better than those in control group with a significant difference ( P<0. 05). There were statistically significant differences in horizontal abduction of shoulder joint, upward abduction of shoulder joint, dorsiflexion of middle finger, distance of seventh cervical vertebra between two groups ( P<0. 05). Conclusions Diversified continuing nursing can effectively reduce complications of breast cancer after modified radical mastectomy and promote function recovery of the upper limb of patients.
